August 11, 2021 – Environment and Climate Change Canada (ECCC) and Innovation, Science and Economic Development Canada (ISEDC) must determine whether the proposed Replacement of the Superior West Weather Radar, is likely to cause significant adverse environmental effects. To help inform this determination, ECCC and ISEDC are inviting comments from the public respecting that determination. All comments received will be considered public and may be posted online.

The Proposed Project

The Government of Canada is modernizing its weather-forecasting infrastructure and will proceed with the replacement of its aging weather radars with new, modern radar systems. This initiative will ensure that Canadians are better informed on changing weather, water, and climate conditions and that they have more lead time to take appropriate actions to protect themselves, their family, and their property from the effects of severe weather.

The purpose of the project is to decommission the existing Superior West Weather Radar, located near Thunder Bay, ON and to install a new weather radar system in Shuniah, ON. The new Shuniah radar will continue to provide coverage for northern Ontario and will consist of a 25 m open lattice steel tower with an 11.8 m diameter radome at the top (sphere covering the antenna) for a total height of approximately 39 m including lightning protection rods. The new radar will operate at frequency of 2850MHz.

The radar is located near 10-140 Tower Road, Shuniah, Ontario P7A 0W2, a property that ECCC requested a transfer of adminstration and control from the Government of Ontario. The geographic coordinates of the proposed radar site are 48.595876°, -89.100129°.
